scsi: qla2xxx: Add build-time size check for VP config IOCB layout

Browse source

Add a BUILD_BUG_ON for struct vp_config_entry_24xx_ext to verify its
128-byte size at compile time alongside the existing 64-byte check for
struct vp_config_entry_24xx.

Document in qla24xx_modify_vp_config() that the ext variant overlays the
base 24xx layout for the first 64 bytes (all fields this helper reads
and writes), so the IOCB can be built through a single struct
vp_config_entry_24xx pointer regardless of the adapter's IOCB stride.
